Monitor turns on then off quickly

Princeton Digital VL2017 Model L203

When I power the monitor on the led turns green and the screen illuminates and then quickly goes dark, but right before it goes dark I see a 1" spectrum of many colors running vertically. then the led goes to yellow. I have opened it up checked the board connections and see nothing burned or discolored. when I power it on with the back open I can see that the backlights are still illuminating for 3 seconds before it turns off. I have tried it on several computers using both the VGA and the DVI connection with multiple different cables. This happened over the weekend and none of the other computers had any problems so I do not know if this might have been a power surge. Does anyone have any Ideas what might need to be fixed or replaced?

    So I feel stupid I took it home and plugged it into my computer and it
    powers on and stays on back lights work great, but you see vertical
    lines all over and more appear when you press the menu button. also
    when you plug it in as a second monitor and tell it to identify the
    pixels get brighter with what would be the number 2. I was wondering
    could it possibly be that the video input board is bad and not sending
    the proper signal to the LCD monitor, possibly the processor chip? both
    cable types give signal to the monitor. the Inverter board only seems
    to go to the back lights so I don't think that could be the problem. I
    also pulled the boards up and looked at both sides, no bad solder
    joints, no bloated caps, nothing burned or discolored.

From your description of the issue, the LCD and or hte inverter has failed. If less than a year old, contact Princeton Digital for warranty repair, if outside 1 year, it is likely cheaper to replace than repair

The monitor shuts off. Turning the power off

the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

Monitor Powers on Blanks screen with Vertical lines

You can't always see where the solder is off .
Sounds like you need to purchase a new video card.
But before you do ,.. go into your control panel and reset everything in the display settings to original.
Advanced- DPI should be at 96 as default then check (drivers) roll back to original drivers (if you are running an ancient version of windows)
restart your cpu
If this doesnt werk ,... you have a bad monitor . ( hope you kept the reciept).

Princeton Monitor VL1917 - No Power

This is the way how to examine what's wrong with your LCD monitors. After you turned your pc on, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Looks like one of your backlights is bad, first indication is the red or pink tint, replacement of the lamp is fairly easy. If one lamp is bad the inverter will not work. You can get a replacement lamp from Mouser electronics for about $12
